Topic: image manipulation

This episode examines water’s unusual physical properties and research testing whether liquid water can be understood through two distinct structural states. It also explores efforts to identify research misconduct, including image manipulation and fabricated publications, and the tools and post-publication review practices used by independent investigators.

Animal sensory systems are optimally adapted to those features typically encountered in natural surrounds, thus allowing neurons that have a limited bandwidth to encode almost impossibly large input ranges. Importantly, natural scenes are not random, and peripheral visual systems have therefore evolved to reduce the predictable redundancy. The vertebrate visual cortex is also optimally tuned to the spatial statistics of natural scenes, but much less is known about how the insect brain responds to these. We are redressing this deficiency using several techniques. Olga Dyakova uses exquisite im
